Just after I had my battery replaced this summer, my fuel gauge started floating, light comes on even if I have just had it refilled. Then my speedometer cuts out out of the blue. Very annoying and definitely worth mentioning.

This is the third time we've dealt with this problem. First time under warranty second time replaced by dropping gas tank and replacing fuel pump and sensor, now happening again. What's going on?

Envoy XL V8

  • Automatic transmission
  • 60,000 miles


After filling my Envoy with $80.00 in gas this AM, the low fuel light went on & the warning bell started to ding. I had just filled the tank! What the heck? I re-set the gas cap several times and it did not fix the problem. Got my manual out of the glove box, but it was no help.

The further I drove the car down the road - the more gas I had! Nice idea, but that is not how it really works! Did a "Google" search to see what info I could find. Seems to be a re-occurring problem with the Envoy. I love this vehicle. Purchased it new and had planned on keeping it forever! Guess I will make a trip to the dealer and see what they say.

Makes me sad to see that this is a problem for the GM trucks/SUV & no one is getting any assistance with a malfunction that the company is totally aware of. Our family always bought GM cars. My brother-in-law was an engineer for them. We buy American!

  • Automatic transmission
  • 61,000 miles

This problem stated out of the blue. On 12/03/2011 I filled my tank with gas and the gauge went to E and the low fuel light came on and chimed. After I start the vehicle about 5 to 6 times, the gauge appears to read normal, but I can't be sure. I have lived with this problem (and it is a problem not knowing how much gas is in the tank) for several month. I have tried to research what is going on, and it appears GMC knows about this problem, but isn't doing anything about it since the Envoy isn't made anymore.

Update from Feb 12, 2015: I actually paid to have it fix . . . out of my pocket. Apparently GMC doesn't care about customers once the vehicle is purchased and warranty has expired.

Envoy LX V6

  • Automatic transmission
  • 60,000 miles

I travel a lot and this summer has been awful. I was told this problem alone would be over $1,000 to fix. I have to travel with a few extra gallons of gas because we rockhound in remote locations. I never know my fuel level and it is awful!

Its bad carrying gas in my back seat and the smell! Come on GMC, You should be fixing these problems!

Envoy SLT 4.2L V6

  • Automatic transmission
  • 84,000 miles


Let me start like this. My family including my grandfather always had Chevrolet or GMC cars. I was raised learning how strong they were, smooth driving and extremely comfortable. I bought a Chevy trailblazer 2002 in 2006 which i loved, but unfortunately somebody had crashed and after fixing I sold. Next, I decided to buy an Envoy SLT V6 2005 with 27Kmiles in 2008, which I have until today and I love so much. Smooth drive, comfortable, powerful, great looking, spacious and great engine. As my grandfather used to say, "son always have a normal maintenance and this car will last forever". I never had any serious problem, except now that the fuel sensor level is dead and i have the chime always signalizing low fuel even if I fill out the tank. Well i wait for more than 3 months filling out the tank and tracking the mileage. 2 weeks ago I received a letter from GMC with my VIN number standing that this is a problem that they find out and they are willing to pay 50% of the cost. I did call them in fact to know the authenticity of the letter and they confirm the issue recommending to take to the dealer. I did, and this problem has a cost equivalent of almost a thousand, which with 50% of discount with the letter will be close to five hundred. I'm planning to open a complain with GMC to have this paid 100% since it's a recognized issue and they are avoiding to have this is a recall. Please let's create a group of this issue and fill out complains to have this paid for us...my car still has the problem, but i refuse to pay for something that seems to be a recall.

Envoy SLT 4.3L V6

  • Automatic transmission
  • 49,600 miles

Just a day after purchasing this vehicle private party (1/15/11) (1st mistake) we filled the vehicle with gas, and noticed that the fuel level was empty immediately after restarting. It hasn't been that big of a deal (would return to FULL after a few miles) but now (May '11) if the fuel level is below 1/4 tank, the gas gauge will again go to E and go between the two points, not to mention the "Range" will also change as the level fluctuates. This is ridiculous, I would expect more from an American made SUV. Who knows how long before it goes out completely.

Envoy LX 3.2L

  • Automatic transmission
  • 68,000 miles

Well when I filled my vehicle, the empty light came on and dinged 3 times. So I never know how much gas is in my vehicle. I talked to someone I worked with and he has a chevy pickup with the same problem. And then my daughter-in laws mother and I drove 100 miles to see our grandsons x-mas program and she noticed the problem I have with my gas tank and she drives a chevy trailblazer 2009 and she also said she has the same problem. So what are we to do about this? So I noticed there was no recall and I think you may want to check on this and have one. So please get back to me or do we report this as a lemon law? I am not sure, hope you can advise me. Sincerely Rosemarie Pitts

The fuel gauge floats and when you fill up the car, it goes automatically to empty - I never know how much gas is in the car
